LIGHTING ISSUES: If your main issue is light, you could try making a DIY lightbox: http://www.wikihow.com/Create-an-Inexpensive-Photography-Lightbox If your products are too big to fit in a lightbox then consider asking a friend with big windows whether you can take some photos there (you might need to tape white tissue paper to the windows to diffuse the light).

LIFESTYLE SHOTS: Do you take 'lifestyle' photos as well as plain ones? Lifestyle photos means you show how the item might be used, or place some props around it to give it a sense of scale or to invoke an emotion. For example if you make jewellery you don't HAVE to show it on a model (though this could be good) but you could show it draped across a jewellery dish - a modern neon stripe dish with bright white lighting if your jewellery is for the young fashionista, or a vintage saucer dish with warm lighting if your jewellery is for the more mature or softer-styled lady.
